You knew that it was just a matter of time till someone invented an Inception-themed food. Well, that time is now: Elie Ayrouth of Food Beast blog created the Inception Taco. He used 5 different Del Taco menu items to create "five dream levels of burrito for you to traverse with every bite"

Wait till you see the totem on the 4th level of the Inception Burrito: Link

This is taken from the south park episode parody of inception called Insheeption. Basically to try and explain the concept of a dream within a dream, the characters talk about a taco within a taco within another taco etc.
